In any case that provenance would add some value, to the right collector. I was negotiating for a gun, and had a firm price. I went 10% above because of a great tidbit that I learned. I know that they say, "Buy the gun, not the story" but when you buy a historic gun you are certainly also buying the story, real or imagined. You have documentation of one piece of the story. Probably doesn't double the value but I think it is worth ten or twenty percent to the "right" person. My gun story? It was a Smith 32 Hand Ejector, beautiful condition, but there are so many out there and I had a couple. Price was below $300. I had a goal. Price stopped about ten percent above my goal. We kept talking. Seller was 81 years old. He was entering a nursing home. When he said, "It was my mother's kitchen gun" I mentally said, "Stop arguing and buy it!" So I paid a bit above my goal.
